Former Sen. Joseph Lieberman (D-CT), who was Democrat presidential candidate Al Gore’s running mate in the 2000 election, has passed away at the age of 82.

Lieberman’s family announced in a statement that he had died in New York City on Wednesday “due to complications from a fall.”

“His beloved wife, Hadassah, and members of his family were with him as he passed,” the statement explained. “Senator Lieberman’s love of God, his family, and America endured throughout his life of service in the public interest.”

His family scheduled his funeral for Friday, March 29, at Congregation Agudath Sholom in Lieberman’s hometown of Stamford, Connecticut.

Lieberman, who is known for being more of a moderate Democrat, was elected to the U.S. Senate in 1988 following a decade in the Connecticut state Senate and six years as Connecticut’s attorney general.

He has a history of bucking his own party and supporting some establishment Republicans, including backing former Sen. John McCain (R-AZ) for president in 2008. Lieberman even gave a speech in support of McCain’s candidacy at the Republican National Convention just a few years after being the Democrat vice-presidential nominee.

“What, after all, is a Democrat like me doing at a Republican convention like this?” he asked the crowd at the convention. “Well, I’ll tell you what: I’m here to support John McCain because country matters more than party. I am here tonight for a simple reason. John McCain is the best choice to bring our country together and lead America forward.”

Following the news of Lieberman’s passing, numerous prominent figures on both sides of the aisle took to social media to mourn his loss.

“Connecticut is shocked by Senator Lieberman’s sudden passing,” Sen. Chris Murphy (D-CT) wrote in a statement. “In an era of political carbon copies, Joe Lieberman was a singularity. One of one. He fought and won for what he believed was right and for the state he adored. My thoughts are with Hadassah and the entire family.”

Murphy also posted about the news on X, formerly known as Twitter.

Sen. Lindsey Graham (R-SC) also expressed his condolences in a post on X.

“Just heard of my dear friend Joe Lieberman’s passing. As I am just now leaving Israel, so many emotions,” he wrote. “This is devastatingly sad. I feel fortunate to have been in his presence, traveling the world in support of America’s interests as we saw it. To Hadassah, I know your heart is broken, but please understand your legion of friends love you dearly. To the Lieberman family, we will be with you through this journey. I look forward to sharing more thoughts about this wonderful man and the incredible life he lived. The good news, he is in the hands of the loving God. The bad news, John McCain is giving him an earful about how screwed up things are. Rest in peace, my dear friend. From the Last Amigo.”
